"Will and Rob showed up at the house and the appointed time and started right at it. The old a/c, furnace,duct work, wiring, and gas line were gone in no time. When they started the install, took their time to get everything perfect. Constantly checking for level and plum of all units, ducts, plumbing, and even wiring. Explained what was going on and why they were doing what they were doing. Both Will and Rob very friendly and extremely knowledgeable about HVAC. I worked in the plumbing wholesale for 20 years, so I know a bit about was going on. The new technology is amazing. They installed a 96 percent efficient furnace with a 16 seer a/c unit by Amana. Came with a lifetime warranty on the a/c compressor and furnace heat exchanger, the two main components.
They did an excellent job. All the old units were taken away and site was completely cleaned cleaner than before they started. Will even filled out the rebate form from the electric company for me.
I will definitely hire Giant again and again!

"Jason came out and gave us a quote and walked us through how he came to that conclusion. He was very efficient and kind when coming out and installing a new Central Air unit and updating our electrical panel; both done for cheaper than others were quoting to do just the A/C! I was very impressed with the job and with how he respected our property. Any questions I had he was quick to answer and explain in a way that would make sense. If I ever needed anything, I would 100% contact them again!"
